The change in the angle of circular motion is analogous to <u>linear velocity</u> in linear motion
<u>Explanation:</u>
We define angular velocity ω as the rate of change of an angle. The greater the rotation angle in a given amount of time, the greater the angular velocity. angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time.
The units for angular velocity are radians per second (rad/s). Angular velocity ω is analogous to linear velocity v. Linear velocity is the measure of “the rate of change of displacement with respect to time when the object moves along a straight path.” It is a vector quantity.
We know density = Mass / Volume
So Volume = Mass/Density
Volume = Area * Thickness
So the approximate thickness of the foil in millimeters = 
Answer:
Fm - W = 0 1) true. Imams must separate, to match the two forces, you reach equilibrium
Explanation:
When the magnet is exchanged for a stronger one, but of the same weight, the equilibrium equation
Fm - W = 0
Fm = W
If the weight of the imam is the same, the magnetite force must decrease, so that it will occupy the magnets must be separated a greater distance, according to the formula
Fm = Km m ’m / r²
Where Km is value 10⁻⁷ N s²/C², r is the distance between the poles
Let's review the proposed results
1) true. Imams must separate, to match the two forces, you reach equilibrium
2) False. In this case the weight would be less than the magnetic force
3) False The magnetic force increases and equilibrium is not reached
